 // WindowSizeAutosaver is a helper class that makes it easy to let windows
 // autoremember their position or position and size in a PrefService object.
-// To use this, add a |scoped_nsobject<WindowSizeAutosaver>| to your window
+// To use this, add a |base::scoped_nsobject<WindowSizeAutosaver>| to your
+// window
 // controller and initialize it in the window controller's init method, passing
 // a window and an autosave name. The autosaver will register for "window moved"
 // and "window resized" notifications and write the current window state to the
 // prefs service every time they fire. The window's size is automatically
 // restored when the autosaver's |initWithWindow:...| method is called.
 //
 // Note: Your xib file should have "Visible at launch" UNCHECKED, so that the
 // initial repositioning is not visible.
